CHARLES T. SHADBOLT, OF AllTICA, Nit-YV YORK..

CHU-RN.

SPECIFICATION forming part of Letters Patent No. 309,410, dated December 16, 188%.

Application tiled May 17, 1Std. (No model.)

To @ZZ whom i may concern:

2c it known that l, @Harnais .l. Snjrnnorfr,

of Attica, in the county of Vyoming and State of New York, have invented new and useful Improvements in Ghurns, of which the following is a specification, reference being had to the accompanying drawings.

rlhis invention relates more especially to that class of churns which contain horizontal flasher-arms revolving around a perpendicular shaft and passing through the spaces between stationary breaker-arms, which are secured to the inner side of the tub-as, for instance, in the churn described and shown in Letters Patent ofthe United States No. 130,731), dated August 20, 1872.

rlhe object of my invention is to ren'derthe churn more efficient and convenient in operation; and it consists of the particular construction oif the means whereby the bar carrying the stationary arms is secured to the inner side of the tub, as will be hereinafter fully set forth.

ln the accompanying drawings, Figure l is a side elevation of myimproved churn. Fig. 2 is a vertical section at rightangles to liig. il; Fig. 3 is a top plan view ot` my improved churn with a part ofthe cover removed. Fig. et :is a perspective view of a pair of dasherarms.

Like letters ot' reference refer to like parts in the several iigmures.

.A represents the churn case or tub, of ordinary forni.

B represents the perliicndicular shaft, arranged centrally in the tub A., and supported with its lower end in a step-bearing formed by a screw, l), jnojecting lunvardly through the bottom A ofthe tub. I

.C represents the horizontal dasher-arms, secured to the vertical shaft ll. -The arms G are arranged in pairs upon the shaft IB, each pair being preferably cast in one piece on diametrically opposite sides ot' a common hub, d, through which the shaft i3 passes. The arms l are curved forwardly,or in the direction in which they move,whereby the cream is moved toward the middle of the tub. The front or face side ot' each arm is made concave, as shown at e, and its rear side is made convex,

l l l parallel with t-he concave face, as shown at j. By this construction ofthe arms the waves which are caused by them, and the open airspaces in the rear of these. waves, are increased in size, and a more intimate contact of the air with the butter-globules is effected thereby. rllhe several pairs of arms are arranged on the shaft B, one above the other, at suitable dista-nces apart, and secured to the shaft by (lowelpins, set-screws, or keys, as may be preferred.

' F represents the stationary breaker-arms, which extend radially from the side of the tub toward the middle thereof, and which are arranged in line with the spaces between the arms C, so that the latter in rotating will pass through the spaces between the stationary arms F. rlhe latter are preferably made diamond-shaped in cross-section, and are east in one piece with an upright strip or bar, G, fitted against the inner side of the tub.

c is a stud or pin projecting from the lower end of the bar (t into a socket, l1., formed in the bottom of the tub, whereby the lower end ofthe bar G is held in place.

is a screw-bolt attached to the upper end ofthe bar G, and projecting outwardly through a slot, l, 'formed in the tub, wherein it is secured by a thrunb-nut7 l. Upon removing the cover of the tub and releasing the thumbnut l. the bar G, with the stationary arms F attached thereto, fan he lifted out of the tub, whereby the cleaning of these parts is greatly facilitated. The slot l is closed to prevent the escape ot` cream. through the same by extending the bar (It up to the cover, or by attaching a strip ol' suitable size to the under side of the cover in a position to close the slot Iwhen the cover is closed.

li represents the bridge-piece, which tends diainetrically across the top of the tub, and which is provided with a bearing, 7x1, in which the shaft B `is held.

L is a gear-pinion mounted on the shaft B abovey the bridge-piece K, and M is a gearwheel meshing with the pinion L, and secured to the inner end of ahorizontal shaft, m,whieh is provided at its opposite end with a handcrank, m. rlhe shaft m is supported in bearings n, secured to the bridge-piece li. .The shaft is extended upward beyond the wheel IOO M, and provided with a handwvheel, O, by which the dasher-arms may be rotated when the consistency of the material in the churn reaches a point where their rotation by means ot' the crank m/ becomes inconvenient or impracticable.

l? represents the legs on which the tub A rests. They are each composed of two bars, p, which are secured. With their upper ends to the bottom of the tub, and a central bar, p',

which is secured with its lower end to the bars p at their junction, and with its upper end to the outer side of the tub, so as to servo as a brace, the three bars together forming a light and rigid leg. 15

I claim as my inventionrlhe combination, with the tub A, provided with the slot I and socket 7L, of the removablev bar G, provided with arms F, stud g, formed at the lower end of the bar G,screw-bolt i, at- 2o tached to the upper end of the bar G, and thumb-nut l', substantially as set forth.
